does not have a phonemic function in English)

Here is the vowel quadrilateral divided into sectors with the IPA symbols at fixed points. These are called Cardinal Vowels.

N.B. Do not confuse symbols for cardinal vowels with language specific phonemes

The IPA vowel quadrilateral is a grid on which we can plot vowels

It indicates the total area in which vowels can be produced by human beings, the cardinal vowels are fixed reference points on this chart, just like lines of longtitude and latitude on a map

Plots of language specific vowels do not usually correspond to the cardinal vowels, e.g. the Italian /a/ does not correspond to the cardinal vowel [a]

Generally, front vowels are unrounded and back vowels rounded…

Italian and English follow this pattern…
